Resize windows pop-up blank firewall alert

Running win7x64 Ultimate. If I attempt to resize a window, I get a blank pop-up from Comodo firewall asking whether to accept or deny it. it took quite some time to pinpoint the cause. I attach a screenshot. this happens 100% of the time.

bump – is anyone else experiencing this? I uninstalled and reinstalled the latest version – no improvement.

Doesn’t happen on Win7 x32 here, but i guess you have to wait untill v4 beta comes out, it will probably still contain this bug, but then there will be a next round of non-major bug fixing. At the moment they are only working hard to get v4 out and these bugs probably will have low(er) priority…
